I read a lot of theories about black holes and cant help but wonder if they are "holes" at all. What if the center of a black hole is just an element that is created by the immense pressure at the time of the supernova? An element so dense would not be able to be seen and would appear as a black spot or hole due to the fact it even pulls in light. All the matter pulled into it is crushed into the new element and again, because it is so dense that light cannot escape its gravitational pull we cannot see this process.
I have not found this type of question answered or even really asked which makes me think I'm overlooking something but I wanted to throw it at the wall and see what other opinions or answers I could find.
